## San Francisco Giants at Pittsburgh Pirates

*Logan Webb (RHP): 83% NRFI, 3.72 ERA, 1.10 WHIP, 7.2 K/9, 2.2 BB/9, NRFI streak of 6. Paul Skenes (RHP): 74% NRFI, 3.79 ERA, 1.12 WHIP, 10.9 K/9, 2.5 BB/9, NRFI streak of 4. First pitch 6:40 PM ET at PNC Park (730 ft).*

Neither starter hands out early traffic, and in the first inning that is most of the battle. Logan Webb runs a 2.2 BB/9 and Paul Skenes a 2.5 BB/9, so a walk is unlikely to spark the run this bet is fading. Paul Skenes is the softer side at 74% NRFI, but he only has to be ordinary in the first for this to cash. Logan Webb is trending up as well, a 2.87 ERA across his last five starts against a 3.72 season mark. The lean is NRFI, carried by the stronger arm.

## Athletics at Texas Rangers

*J.T. Ginn (RHP): 79% NRFI, 3.71 ERA, 1.24 WHIP, 7.9 K/9, 3.7 BB/9. MacKenzie Gore (LHP): 71% NRFI, 4.40 ERA, 1.28 WHIP, 10.0 K/9, 3.4 BB/9, NRFI streak of 3. First pitch 8:05 PM ET at Globe Life Field, indoor.*

J.T. Ginn anchors this one at 79% NRFI, and the combined 58% rate keeps the game in play as a lean. MacKenzie Gore is the softer side at 71% NRFI, but he only has to be ordinary in the first for this to cash. The lean is NRFI, carried by the stronger arm.

## Seattle Mariners at Boston Red Sox

*Bryan Woo (RHP): 80% NRFI, 4.36 ERA, 1.10 WHIP, 9.0 K/9, 1.9 BB/9. Sonny Gray (RHP): 68% NRFI, 2.82 ERA, 1.18 WHIP, 8.0 K/9, 2.3 BB/9. First pitch 6:45 PM ET at Fenway Park (20 ft).*

Neither starter hands out early traffic, and in the first inning that is most of the battle. Bryan Woo runs a 1.9 BB/9 and Sonny Gray a 2.3 BB/9, so a walk is unlikely to spark the run this bet is fading. Sonny Gray is the softer side at 68% NRFI, but he only has to be ordinary in the first for this to cash. Bryan Woo's 1.9 BB/9 means the leadoff man rarely reaches, and empty bases in the first almost always mean a zero. A thin NRFI lean at best.

## Honorable Mentions

- **San Diego Padres at Cincinnati Reds:** Randy Vásquez riding a run of 6 scoreless first innings.
- **New York Yankees at Los Angeles Angels:** Gerrit Cole riding a run of 9 scoreless first innings.
- **Toronto Blue Jays at Cleveland Guardians:** a combined 53% NRFI rate.

## Games to Avoid

These matchups carry the highest first inning scoring risk on tonight's slate.

**Baltimore Orioles at Colorado Rockies.** Coors does what Coors does. At 5,200 feet the ball carries, and even the better arm here gives back margin in the first. Leave this one alone.

**Detroit Tigers at Minnesota Twins.** Connor Prielipp's 5.55 ERA tells the story, vulnerable early and often. Leave this one alone.

**St. Louis Cardinals at Los Angeles Dodgers.** Eric Lauer is the weak link at 53% NRFI, and the combined 41% rate sits near the bottom of the slate. We are passing here.

## Before You Lock

Confirm the starting pitchers on the [NRFI dashboard](/mlb/nrfi). A bullpen game kills NRFI value immediately. Check the weather at first pitch and be careful at altitude, Coors in particular. NRFI bets land 55% to 65% of the time historically, and you need roughly 52.4% to break even at minus 110 odds.
